PLOW.

Application filed January 18, 1924. Serial No. 686,994.

To all whom t may concern.'

Be it known that 1, MARTIN KELP, a citi- Zen of the United States, residing at Paris, in the county of Stark and State of Ohio, have invented a new and useful Flow, of which the following is a specification.

This invention relates to improvements in plows, and more especially to a plow known in the art as a reversible or hillside plow.

One object of this invention is to produce a highly practical plow of the character indicated in which the mold-board of the plow is pivotally connected to the standard and has its axis substantially parallel with the draft-line of the plow, and to enable the mold-board, upon raising said standard, to be actuated circumferentially of said aXis and under the standard from its position at one side into position at the opposite side of the plow.

Another object is to render the connection between the mold-board and the standard simple and durable in construction, and to provide simple and inexpensive means'for holding the mold-board and attached plowshare in the required position.

Another object is to attach and it the plow-share to the mold-board in such a manner that, in plowing, there is no liability of loosening or displacement of the plowshare in relationl to the mold-board, nor strain upon the bolts or screws employed in securing the plow-share to the mold-board.

Another object is to so contour and relatively airange the plow-share and moldboard that the plow shall operate more uniformly and with greater efficiency than hillside plows heretofore made, and that the mold-board and plow-share shall adequately cooperate in turning over the furrow-slice and in the breaking up ordisintegration of turned up lumps of earth.

Another object is to facilitate the assemblage of the component parts of my improved plow, and to reduce, to a minimum, the strain upon said parts during the operation of the plow.

With these objects in view, and to attain any other object hereinafter appearing, this invention consists in certain features of construction, and combinations and relative arrangements of parts, hereinafter described in this specification, pointed out in the claims, and illustrated in the accompanying drawings.

In said drawings, Figure 1 is a. side elevation, partly in section, of the greater portion of a hillside plow embodying my invention. Fig. 2 is a horizontal section taken along the line 2 2 in Fig. 1. Fig. 3 is a section and front view taken along the line 3 8 in Fig. 1. Fig. 4 is a rear end view and shows the mold-board in solid lines at the left-hand side of the plow and in broken lines at the right-hand side of the plow. Fig. 5 is a section taken along the line 5 5 in Fig 4, looking downwardly. Fig. 6 is a side view of the mold-board and attached plow-share. Figs. 7 and 8 are vertical sections taken along the line 7 7 and line 8 8 respectively in Fig. 6, looking forwardly. Figs. 9 and 10 are vertical sections taken along the line 9 9 and line 10-10 respectively in Fig. 6, looking rearwardly.

Rerferring to said drawings, A indicates the draft-beam; B the standard; C, the mold-board, and D, the plow-share.

The draft-beam A is rendered rigid with the standard B in any approved manner, and the provisionof said draft-beam with handles or draft-appliances is too well understood in the art to require illustration and description in this specification.

The mold-board C is shown arranged in Figs. 1, 2, 3, 4 and 5, and in solid lines in Fig. 4, at the left-hand side of the plow.

The mold-board C (see Figs 1, 2 and 5) has a forward end member 15 which extends forwardly of the lower end portion of the standard B, and the share D is seated on and secured vto said member 15 as will hereinafter appear.

The lower end portion of the standard (see Fig. .5) is provided, at the front of the standard, with a forwardly projecting pivotal member 16 which is arranged substantially parallel with the draft-'line of the plow and extends into a corresponding hole 17 formed in the member 15 of the moldboard, and said member 15-has a bearing on said pivotal member. It will be observed, therefore, that the member 15 of the moldboard is pivoted to the standard B and has its aXis substantially parallel with the draft- 105 rod , and said ulxwde comme stamt plovY mold.

board, the abutting of the rear end of said share against the undercut shoulder 36 on the mold-board, the abutting of the undercut shoulder 37 on said share against the forward end face of the member 15 of the mold-board, and the overlapping of the longitudinal edges of the mold-board by members or portions of said share, all participate in forming a simple and durable construction by which strain upon the bolts or screws 39 is successfully prevented. The shoulder 36 on the mold-board is arranged wholly rearward of the pivotal connection 16 between the-standard B and the forward member 15 of the mold-board and preferably wholly rearward of the screws 39, and by the hereinbefore described construction it will be observed that the plow-share is firmly secured to said member of the moldboard and that the rear beveled edge of said share extends transversely of the share at the rear extremity of the seat formed by the side 35 of said member of the moldboard and is overlapped by the undercut shoulder 36 on the mold-board so that said shoulder not only serves as an abutment for and extends longitudinally of said rear edge of the plow-share but also serves tohold the plow-share rigidly, at the rear end of said share, to said seat.

The mold-board C has an outer side 43 which extends rearwardly from the share D and faces laterally outwardly and upwardly and is curved inwardly and transversely to form a' hollow extending rearwardly from the shoulder 36 on the moldboard and gradually increasing in depth in a rearward direction so as to facilitate and cause the passage of more earth to the rear end of the mold-board in plowing.

The share D has a laterally outward-ly and upwardly facing outer surface 45 which is formed between the projecting members 41 and 42 of the share and curved inwardly and transversely and extends forwardly from the forward extremity of the side 43 of the mold-board preferably to the point 40, and said projecting members 41 and 42 diverge outwardly from said surface 45.

To render said side 43 of the mold-board and the surface 45 of the share D capable of cooperating in breaking up or disintegrating lumps of earth passing, during the operation of the plow, from said surface of said share onto said side of the mold-board, the relative arrangement of the parts is such that said side of the mold-board and said surface of said share are flush at the shoulder 36 of the mold-board .and that said surface of said shareand said side of the mold-board diverge somewhat outwardly from their meeting extremities, as shown in Fig. 5.

Preferably the outer part of the rear end portion of each of the flanges 41 and 42 of the share D has a forwardly facing and preferably inwardly curved forward edge 46, and hence the forward edge 46 of the flange which is arranged at the top of said share operates to break up or disintegrate any lump of earth that, during the operation of the plow, may be thrown upwardly against said edge and the forward edge 46 of the projecting member which is arranged at the bottom of said share serves to sever roots and participates in breaking up or disintegrating lumps of earth. The rear end portions of the flanges 41 and 42 of the plow-share are preferably considerably wider than the remainder of said flanges, and the forward edge 46 of the outer part of t-he rear end portion of each flange preferably extends toward the forward extremity of the outer end of said outer part of said portion of the fiange so as to materially enhance the efficiency of said portion of said flange. Also, the shoulder 36 on the mold-board is wholly rearward of the earthdisintegrating forward edges 46 of the rear portions of the flanges 41 and 42 so as to minimize, while plowing, undue accumulation or conges-tion of earth or material on the mold-board next rearward of and in proximity to said shoulder.

My improved hillside` plow, by virtue of the hereinbefore described structural peculiarities and relative arrangements of parts, is remarkable for its uniformity of operation and great efficiency in plowing, and is adapted to effect a greater disintegration of lumps of turned-up earth and permit less earth to be thrown upwardly against or above the plow-beam than hillside plows heretofore devised.

That I claim is- 1. A plow comprising a standard, a moldboard arranged in the main at one side of and supported from the standard and having a forward member which extends forwardly of the lower end portion of the standard and has a forwardly facing end face and an upwardly and laterally outwardly facing outer side, and a plow-share seated on said side and extending forwardly of said forward member of the mold-board and having a rear transverse edge at the rear extremity of said side of said member of the mold-board, the mold-board having a forwardly facing shoulder at and opposite said edge of the plow-share and also having` an outer side which extends rearwardlyl from said shoulder and faces upwardly and laterally outwardly, and the plow-share having a rearwardly facing shoulder abutting against the aforesaid face and being secured, between said shoulders, to the aforesaid forward member of the mold-board.
